What are some examples of functional programming in C#?

Functional programming in C# includes using delegates, lambda expressions, and LINQ. Would you like to see specific examples?

Yes, please provide an example using LINQ.

Sure! Here's a simple example:

var numbers = new List<int> { 1, 2, 3, 4, 5 };
var squaredNumbers = numbers.Select(n => n * n);

This code squares each number in the list using a lambda expression.

That's great! Can you explain how delegates work in functional programming?

Absolutely! Delegates are type-safe function pointers. They allow you to pass methods as parameters. For example:

public delegate int Operation(int x, int y);
Operation add = (a, b) => a + b;
int result = add(5, 3);

This code defines a delegate for an operation and uses a lambda expression to implement addition.
